Implementing Exploration Archives for data management and online storage
OMV Group is one of Austria's largest listed industrial companies. The OMV Upstream business segment operates in 20 countries around the world and has a considerable seismic library.
In 2013, the OMV seismic data management infrastructure included an internal hierarchical storage management (HSM) system for archiving processed SEGY data, vendor proprietary archiving software and an aging metadata application.
With the metadata on an aging application and SEGY data stored in vendor's proprietary format, OMV needed a solution.
OMV contracted OvationData to address the challenges and provide a solution that ensured a productive workflow and secured the integrity of the seismic data library.
OvationData's solution included three key elements:
- Replace the existing metadata application with a modern seismic data management software, Exploration Archives
- Convert the data from the vendor's proprietary format to a common and unencumbered readable format
- Host the processed data at OvationData's datacentre
Multi-client data management
Petroleum Geo-Services (PGS) is one of the largest global providers of multi-client seismic data. With 12 offshore vessels and 30 offices worldwide, PGS operations create large volumes of multi-client seismic data to add to its ever-increasing library.
In 2013, PGS began evaluating the options available for improving the management of their seismic library on a global level.
OvationData's highly skilled technicians use specialised software to provide the client with complete datasets in a modern format. We rationalised datasets from more than 10,000 wells for a variety of fields, some dating from the 1950s.
In conjunction with the digitising project, the client commissioned OvationData to perform data processing for an exploration project. We provided vectorising, depth matching and compositing services to combine data of all vintages. Working closely with the client, we resolved issues inherent in combining historical data for use with modern software.
OvationData's advanced methods, facilities and geophysical experts contribute to the success of this historical digitising project.
Our trained technicians began investigating each digital file to establish an inventory of the information included with the data. We repaired many damaged files and reformatted the data to extract the curves required by the client for their project.
We identified the possible duplicate files and performed comparison activities to confirm if the duplicate files were identical. For files that were not identical, we determined which file contained the most reliable datasets.
For the scanned well logs, our technicians performed an assessment on the files that had missing digital well log data and established a list of files that could be used to expand the dataset with vectorisation. Using our proprietary DiplomatTM Wellman software, we vectorised scanned images and improved the quality of the final datasets.
After compiling and preparing the collection of data files, we created composited files by depth matching, splicing and merging log runs into a single file.
Based on previous successful projects with Wintershall Noordzee, OvationData was awarded this transcription project. The seismic data was originally stored on 31,800 cartridges of various types, and 3,000 9-track open reel tapes. To meet the storage requirements for the project, our scope of work included the required processes for migrating the data to high-density IBM® 3592 cartridges.
OvationData received the full inventory of media with Wintershall's standard tape storage boxes and generated a run-list for each box. Using specialised software, we created copies of the data on internal disk space.
Using the legacy inventory, we identified all datasets, located the data in virtual boxes and organised it into products. During the quality control procedures, OvationData performed strategic processes to achieve the quality requirements for the field data, gathers data, processed data and P1/90 navigation data.
For field data, OvationData concatenated the data to ensure no line was split across outputs on the 3592 media. We produced shot record displays for each line at 500 shotpoint intervals. To verify that the complete survey was transcribed, we checked the shotpoint line range against P1/90 navigation data.
For gathers and gathers data sets, we binned the data. We generated near, mid and far trace cubes together with time slices and fold coverage displays.
For processed data sets, we generated time slices and the root mean square (RMS) amplitude value displays. Using these displays, we validated the integrity of the data and identified discrepancies in the transcription data to be restored.
For P1/90 navigation data, we created sail line maps and coverage plots. We created coverage plots for all BIN data sets. For all other data types, such as interpretation and raw navigation, we encapsulated in RODE format to preserve the native formats.
OvationData transcribed the large volume field and gathers data to 3592 cartridges, and produced a back-up copy. We wrote the processed data to TAR format at one megabyte (1MB) block lengths to 3592 cartridges.
The AVATAR-m project aims to bridge the gap between archiving as a long-term preservation activity and the role that archives have as working repositories of an organization's most valued assets. The scope of the AVATAR-m project is to produce a set of products that provide an innovative approach to planning and managing large-scale, sustainable and integrated digital archive solutions.
Throughout the project, OvationData works with companies, institutions and universities with a range of technical expertise and a common interest in long term audio and visual preservation.

Typically post-production companies make huge investments in in-house infrastructure to maintain high resource capacities. The scale, complexity and turnaround time of post-production work places high demand on rendering resources and activities. The result is high costs, wasted power and organizational inefficiency, a situation that is rapidly becoming unworkable.
MUPPITS aims to development a structure that facilitates collaborative work by combining resources in a mutually beneficial business environment.
